Atlatlahuacan Wastewater Treatment Plant, Atlatlahucan, Morelos

The Atlatlahuacan wastewater treatment plant serves the community of Atlatlahucan in the state of Morelos, Mexico. With a design capacity of 1,728 cubic meters per day, the plant treats wastewater from approximately 8,215 residents, operating at a secondary treatment level. As a secondary treatment facility, the plant employs biological processes to reduce organic matter and suspended solids. In Mexico, wastewater treatment plants are regulated under the National Water Law and NOM-001-SEMARNAT-1996, which sets discharge limits for pollutants. For a community of this size, secondary treatment is standard to meet environmental standards. The treated effluent is discharged into local water bodies that eventually drain into the Balsas River basin, one of Mexico's major river systems. The plant plays a key role in protecting water quality in the region, supporting downstream ecosystems and agricultural water use.

The plant discharges into local streams that flow into the Balsas River basin, which drains into the Pacific Ocean. The Balsas River supports diverse aquatic life and is important for irrigation in Morelos. Protecting this watershed helps maintain water quality for communities and ecosystems downstream.
